You can provide more than one constructor in a class. All constructors have the same name (the name of the class), but different constructors must take a different number of arguments or different argument types
Program to initialize array of objects in C++ using constructors #include <iostream>#include <string>usingnamespacestd;classperson{private:string name;intage;public:// default constructorperson() { name="N/A"; age=0; }// parameterized constructor with// default argumentperson(string name,intage...
A copy constructor is called when an object is passed by value. Copy constructor itself is a function. So if we pass argument by value in a copy constructor, a call to copy constructor would be made to call copy constructor which becomes a non-terminating chain of calls. Therefore compiler...
Default constructor is also known as zero argument or no argument constructors. It is used to initialize data members of class. It does not have any argument. Note that - If we do not create constructor in user defined class. Then compiler automatically inserts a constructor with empty body ...
A constructor in C# is called when a class or struct is created. Use constructors to set defaults, limit instantiation, and write flexible, easy-to-read code.

Here is the following example for Overloading the default Constructor in C++.Open Compiler #include <iostream> using namespace std; class MyClass { public: int a, b; // Default constructor (no arguments) MyClass() : a(0), b(0) { cout << "Default constructor called" << endl; } ...
The base class constructors are called in order of derivation—for example, if ClassA is derived from ClassB, which is derived from ClassC, the ClassC constructor is called first, then the ClassB constructor, then the ClassA constructor....
@Donna In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments. A constructor is called depending upon the number and type of arguments passed. While creating the object, arguments must be passed to let compiler know, ...
In C++, a constructor has the same name as that of theclass, and it does not have a return type. For example, classWall{public:// create a constructorWall() {// code} }; Here, the functionWall()is a constructor of the classWall. Notice that the constructor ...
